Just to add the aerial rods (or squashed Xs) should be horizontal polarisation.

Can't find any reported faults at present for the Mynydd Machen transmitter.
Have you checked your aerial still looks intact and is pointing correctly and that the coax downlead isn't flapping about in the wind?
Also check all the connections behind your TV.
Have your nearby neighbours got no signal?
If neighbours don't have signal either, try phoning the BBC.

There is also this -

Do NOT Retune if you have No Signal - you cannot tune to signals that aren't there (whatever the cause), the usual result is to clear the correct tuning you had.
If you have already retuned and still have no signal, try a manual tune on the following UHF channels for the Mynydd Machen transmitter. UHF C23, C26, C29.

True, but then the site owner doesn't appear to have done any updates of late (not that we've noticed anyway!). The spam filtering has gone down the drain, the "Your comments" page is over-burdened with spam posts, you miss any real ones, and my weekly emails regurgitate posts I made yonks ago, I don't really bother to read them any more. Shame. This was an excellent site.

The Spam bots didn't used to be that much of a problem, it's ever since a site server software update (upgrade?).
There are two of us friendly people that tend to respond regularly on the site, you've just had a response from the other one :) and there's an occasional third who's very good on terrain plots and the likes.
I've not been able to contact the site owner in recent times through channels that used to work, but I also know he had some health problems, so maybe that's why some rather obvious things haven't been resolved. We muddle through as best we can.
I've started looking at the "Can you help" section of the menu in case I can spot a post we may have missed due to the sometimes very long list of spam on "Your comments", but what appears there is an automated thing and often depends on whether someone (maybe us) asked a question - which may have already been dealt with.
The disappointing thing is often, those that had a problem and asked a question, don't always come back and tell whether our reply helped or answer further questions because we need more info. Maybe they just forgot where the posted sometimes so don't see the response, but that isn't uncommon, I've seen it elsewhere as well!

Just to add that the TV transmitter is a "line-fed" relay of Wenvoe.

Hi. Sandy Heath is 18km from you, compass bearing 81 degrees (9 deg short of due E).
You should get excellent reception.
Ideally you need a Group K aerial, though a wideband would do, but might leave you vulnerable to interference from any new/upgraded mobile phone mast using the 700MHz band. There's at least 9 masts within 1.5km of your postcode.
If you suffer interference, you may need a Free Filter from Restore TV, you should have had a postcard from them.
Sandy Heath Grid Reference is TL 20472 49446
